Title: Method and apparatus for performing packet loss or frame erasure concealment
Inventor: KAPILOW DAVID A
IPC: G10L21/02
Filed: 2000-04-19
Granted: 2005-10-11
Abstract: The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder. A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

IPC: B05B12/16
Filed: 2001-06-19
Granted: 2007-01-09
Abstract: In a color A area coating stage, color A paint is coated on a vehicle body to form a color A coating (PA). In a next border zone coating stage, a border zone coating (PBl) is formed by means of a rotary atomizing head type sprayer unit which is tilted with respect to a coating surface of the vehicle body and adapted to spray color B paint toward the vehicle body solely by centrifugal force.      In a succeeding belt zone coating stage, a belt zone coating is formed continuously from the border zone coating (PBl) by means of a tilted rotary atomizing head type sprayer unit.      In a next remainder area coating stage, a remainder area coating is formed on remaining areas of the coating surface continuously from the belt zone coating. By these arrangements, sprayed color B paint particles are allowed to deposit and settle on the vehicle body without rebounding when applying the border zone coating (PB), forming a clear and well-defined border line (BL).
